  • Publication number: 20240042125
    Abstract: A cassette for use with a pumping apparatus having a pumping system for engaging a pump set includes a cassette body configured for releasable attachment to the pumping apparatus to mount the cassette on the pumping apparatus. The cassette body has at least one mounting formation. At least one identification member is mounted on the cassette body by the mounting formation of the cassette body. The identification member and mounting formation are formed to mount the identification member in any one of a plurality of predetermined orientations. Each predetermined orientation indicates a different functional configuration of the pump set.

  • Patent number: 9820916
    Abstract: A flow control apparatus adapted to receive a feeding set includes a housing capable of receiving at least a portion of the feeding set. A pumping device is supported by the housing and positioned to contact the feeding set when the feeding set is received by the housing so the pumping device acts on the feeding set to produce fluid flow in the feeding set for delivery of fluid to a subject. An ultrasonic sensor is supported by the housing and arranged with respect to the pumping device to produce a sensor signal indicative of a viscosity of the fluid delivered through the feeding set. A control circuit is in communication with the ultrasonic sensor for receiving the sensor signal from the sensor indicative of the viscosity of the fluid and in communication with the pumping device to control operation thereof.

  • Patent number: 9699816
    Abstract: Described herein are concepts, systems, circuits and techniques for a docking station configured to couple to an enteral feeding pump or other medical device. In one embodiment, the docking station includes a wireless transmitter for communicating data, such as operating parameters and/or status, to a remote monitor over a wireless communication link, to permit remote monitoring of certain pump diagnostics. In some embodiments, the docking station may utilize the wireless communication link to permit control and/or data exchange with the feeding pump. This may be in addition to or in place of the remote monitoring. The pump may also contain a receiver for receiving data such as operating parameter instructions, general operating instructions, and/or commands.
